Picture of myself


I am a scholarship holder of the DFG research training group QuantLA. Before that I worked in the DFG project OCR-D in the area of OCR post-correction. I am interested in formal language theory, especially mildly context-sensitive formalisms and tree languages. My current main reseach topic is combinatory categorial grammar.
